CHURN.

SPECIFICATION forming part of Letters Patent No. 412,250, dated October8, 1889.

Application filed June 17, 1889. Serial No. 314,629. (No model.)

To all whom it may concern: i

Be it known that I, CARL GRAB, of Brooklyn, New York, have invented anImproved Churn, of which the following is a specification.

This invention relates to a churn,the dasherwings of which are revolvedin opposite directions, so that the milk or other liquid operated uponis thorougly agitated.

The invention consists in the various features of improvement more fullypointed out in the claims.

In the accompanying drawings, Figure l is a sectional elevation of myimproved churn. Fig.2 is a cross-section on line 2 2, Fig. 1; and Fig.3, a top view of the gearing.

The letter a represents a suitable vessel having bearings b, in which ishung a shaft 0, re volv'ed by crank (Z. Upon shaft 0 is mountedcrown-wheel e, engaginga pinion f. The pinion engages a gear-wheel h,which in turn meshes into the idler 'i, Fig. 3. The idler t' engages apinion so that in this way the pinion g is revolved in oppositedirection from pinion f. To the gear-wheel g there is connected a splittube j, reaching some distance down into the vessel a. To this tubethere is attached the dasher-wingj, which passes through the split tube,and which is secured in place by a suitable key 7' Through the tube jand through a perforation of wing j there passes the dasher-shaft k,revolved by crown-wheel f, and having its lower bearing in the bottom ofvessel o To the lower part of shaft it there is secured the wing is. The

wings j is will be revolved around vertical axes, but in oppositedirections, as indicated by the arrows.

The shaft 0 carries a pulley Z, which imparts motion to a horizontalshaft m, hung across vessel to between wings j k. The transmission ofmotion is effected, preferably, by band at and pulley 0, the latter faston shaft 012. The shaft m is hung a little sidewise of shaft 7c, Fig. 2,so as to clear the latter. To the shaft m are secured, at opposite sidesof shaft is, the wings m. These wings will thus be made to revolvearound a horizontal shaft, or at right angles to both the wings j andIt.

It will be seen that in my improved churn the milk or other liquid actedupon is subjected to the action of three different wings 7", 7t, and m,all revolved in different directions. Thus a thorough agitation of theliquid takes place.

W'hat I claim is 1. The combination of the vessel a,with an uprightdasher-shaft, a surrounding tube, and

a horizontal clasher-shaft, and with wings secured to the tube and theshafts, means for revolving the upright dasher-shaft and the tube inopposite directions, and means for revolving the horizontaldasher-shaft, all substantially as specified.

2. The combination of the vessel a,with tube j, projecting partly intosaid vessel and car rying wings j, and with shaft .710, passing throughsaid tube and carrying wings 7s, and with a power-shaft and a train ofgearing for revolving the tube j and shaft in opposite directions, andwith transverse shaft m, carrying wings m, and revolved from thepowershaft at right angles to shaft is, substantially as specified.
